Title: Manufacturing device for electrophotographic sensitive body
Inventor: MATSUYAMA TOSHIROU
IPC: G03G5/08
Filed: 1984-03-13
Abstract: PURPOSE:To reduce the size of a vacuum tank by arranging a high frequency electrode which applies a high frequency potential between a high frequency electrode and a photosensitive body base in a vacuum tank and generates plasma at a fine distance from a vacuum tank wall. CONSTITUTION:A drum 10 as the photosensitive body base is set longitudinally in the center in the vacuum tank 11, which is grounded. The RF electrode 12 is arranged nearby the internal wall of the vacuum tank 11 and the interval (a) between the wall of the vacuum tank 11 and the electrode 12 is less than several mm.. The electrode 12 is connected to the RF terminal of the matching box 13, which is composed of a tank circuit which supplies high frequency electric power from an RF power source to the electrode 12 by capacitive coupling. A capacitor 13 connected to the RF terminal side adjusts the frequency of the tank circuit. The RF potential is applied between the drum 10 and vacuum tank 11 through the box 13 to generate a high frequency electric field and the reaction gas in the vacuum tank 11 is ionized to generate plasma, so that a photosensitive film is grown on the drum 10. Thus, the vacuum tank 11 is reduced in size.

Inventor: ITO TAKAYUKI
IPC: B29C45/37
Filed: 1994-03-18
Abstract: PURPOSE:To markedly reduce residual strain of a molded article and obtain a good molded article even in the case where molding is performed at ordinary mold temperatures by a method wherein apparent thermal conductivity is specified at least at a part of a cavity surface with which molten resin is brought into contact. CONSTITUTION:An injection mold has a movable mold 1 and a fixed mold 2, and a cavity part of the movable mold 1 is designed so as to freely move back and forth with respect to the fixed mold 2. At least a part of a cavity surface with which molten resin is brought into contact is made to have apparent thermal conductivity of 0.05 to 15kal/m.H. deg.C. By setting the apparent thermal conductivity in this range, residual strain of a molded article to be obtained is markedly reduced. This mold is used, and molten resin is injected into the cavity under a state that the cavity is a little opened. While the movable mold 1 is being pressed against the fixed mold 2, the molten resin is spread. Then, the feed of the molten resin is stopped and, while the movable mold 1 is further being pressed against the fixed mold 2, the molten resin in the cavity is cooled for hardening.

Title: Speaker
Inventor: FUJIWARA SUSUMU
IPC: H04R7/20
Filed: 1984-03-14
Abstract: PURPOSE:To attain excellent linearity, miniaturization and thin profile by clipping and holding a disphragm with two same shaped support members in place of conventional speaker edge and damper. CONSTITUTION:The support members 10 where plural wave shapes or wedge shapes are formed to both inner and outer side faces as bellows ring structure are used in place of conventional speaker damper 6 and edge 9, and the two members are placed so as to clip a flat diaphragm 8. When the flat diaphragm 8 is moved vertically, the two support members 10 are expanded and contracted vertically. Since this expansion and contration is excellent when the flat diaphragm 8 is vibrated at a large amplitude at a low output sound pressure frequency charactericstic, excellent linearity is obtained. Since the structure of the speaker is different from a conventional speaker where the edge 9 is placed at the outer side of the entire circumference of the diaphragm 8 by using the member 10, the speaker is miniaturized and the thickness of fram is made thin in comparison with the speaker using the damper 6 and edge 9.

Respective shells are arranged around the center pillar and temperature in the foot warmer is controlled by the temperature regulator 7 in the unit shell 5a normally, therefore, the temperature distribution therein is not made uneven. When the temperature of the unit shell 5b is risen suddenly, the temperature regulator 7 in the unit shell 5b controls it. When a trouble is caused under the ON condition of the temperature regulator 7, the temperature over-rise preventer 8 stops the conduction of the foot warmer.
